"The Comet Game" is based on the idea that Halley's Comet brings bacterial life capable of threatening Earth. The player takes control of a high-tech spaceship tasked with intercepting the comet and eliminating the threat. The mission involves managing multiple tasks at once: enemy missiles must be destroyed before they hit the ship, communication with Earth must be maintained by aligning the comms beam correctly, and the ship's computer system must be kept stable by adjusting a line of LEDs to match the displayed values. A rather unusual but vital task is ensuring the crew's morale – by brewing coffee and injecting it into the crew members, who are in suspended animation.
